As a result, it has become difficult for viewers to find content that suits their tastes from various contents provided by a plurality of businesses. Thus, conventionally, a technique for recommending content that meets the viewer's preference from among content provided by a plurality of businesses has been proposed (for example, Patent Document 1).
　特許文献１では、放送メディアとして地上デジタル放送及びＢＳ／ＣＳデジタル放送だけでなく、ＩＰ（Ｉｎｔｅｒｎｅｔ　Ｐｒｏｔｏｃｏｌ）ネットワークを利用したＩＰ放送及びＶＯＤ（Ｖｉｄｅｏ　Ｏｎ　Ｄｅｍａｎｄ）も対象にした番組推薦機能を有する放送受信システムが提案されている。特許文献１に記載された放送受信システムは、各放送メディアにて放送される番組情報を取得して番組情報データベースに蓄積するホームゲートウェイ装置と、電波を用いた放送、ホームゲートウェイ装置を介したＩＰ放送などのコンテンツを受信する放送受信端末装置とを備える。ホームゲートウェイ装置は、例えば、放送受信端末装置から受信したチャンネル選択情報とユーザ識別情報とを基に、ユーザ毎の番組の視聴傾向を示すユーザプロファイルを作成する。そして、蓄積している番組情報データベースの中から作成したユーザプロファイルに適合する番組を検索して推薦番組一覧を作成し、対応するユーザに送信する。これにより、特許文献１に記載の放送受信システムでは、すべての放送メディアで放送された番組に対するユーザの視聴傾向を示すユーザプロファイルを生成することができ、このユーザプロファイルに基づいて番組を推薦できる。 In Patent Document 1, broadcast reception having a program recommendation function for not only terrestrial digital broadcasting and BS / CS digital broadcasting as broadcast media but also IP broadcasting using an IP (Internet Protocol) network and VOD (Video On Demand). A system has been proposed. The broadcast receiving system described in Patent Document 1 includes a home gateway device that acquires program information broadcast on each broadcast medium and stores it in a program information database, broadcasting using radio waves, and IP via the home gateway device. And a broadcast receiving terminal device that receives content such as broadcast. For example, the home gateway device creates a user profile indicating a viewing tendency of a program for each user based on channel selection information and user identification information received from the broadcast receiving terminal device. Then, a program that matches the user profile created from the stored program information database is searched to create a recommended program list and transmitted to the corresponding user. Accordingly, the broadcast receiving system described in Patent Literature 1 can generate a user profile indicating a user's viewing tendency with respect to a program broadcast on all broadcast media, and can recommend a program based on the user profile.

　［映像コンテンツ受信方法］
　次に、本実施の形態に係る映像コンテンツ受信方法について、図面を用いて説明する。 [Video content reception method]
Next, the video content receiving method according to the present embodiment will be described with reference to the drawings.
　図７は、本実施の形態に係る映像コンテンツ受信方法の一例を示すシーケンス図である。 FIG. 7 is a sequence diagram showing an example of the video content receiving method according to the present embodiment.
　図７に示される例では、まず、ユーザは、ＴＶ１４において、第１コンテンツ保持装置２１が保持する第１映像コンテンツ２１ａを視聴する。より詳しくは、ユーザが選択した第１映像コンテンツ２１ａが第１コンテンツ保持装置２１から映像コンテンツ受信システム３０に送信される（Ｓ３０）。映像コンテンツ受信システム３０は、受信した第１映像コンテンツ２１ａをＴＶ１４に出力する（Ｓ３１）。 In the example illustrated in FIG. 7, first, the user views the first video content 21 a held by the first content holding device 21 on the TV 14. More specifically, the first video content 21a selected by the user is transmitted from the first content holding device 21 to the video content receiving system 30 (S30). The video content receiving system 30 outputs the received first video content 21a to the TV 14 (S31).
　ここで、映像コンテンツ受信システム３０は、受信した第１映像コンテンツ２１ａに関する第１視聴情報を生成し、記憶部５０に保存する（Ｓ３２）。 Here, the video content receiving system 30 generates first viewing information related to the received first video content 21a and stores it in the storage unit 50 (S32).
　次に、ユーザは、ＴＶ１４において、第２コンテンツ保持装置２２が保持する第２映像コンテンツ２２ａを視聴する。より詳しくは、ユーザが選択した第２映像コンテンツ２２ａが第２コンテンツ保持装置２２から映像コンテンツ受信システム３０に送信される（Ｓ３３）。映像コンテンツ受信システム３０は、受信した第２映像コンテンツ２２ａをＴＶ１４に出力する（Ｓ３４）。 Next, the user views the second video content 22 a held by the second content holding device 22 on the TV 14. More specifically, the second video content 22a selected by the user is transmitted from the second content holding device 22 to the video content receiving system 30 (S33). The video content receiving system 30 outputs the received second video content 22a to the TV 14 (S34).
　ここで、映像コンテンツ受信システム３０は、受信した第２映像コンテンツ２２ａに関する第２視聴情報を生成し、記憶部５０に保存する（Ｓ３５）。 Here, the video content receiving system 30 generates second viewing information related to the received second video content 22a and stores it in the storage unit 50 (S35).
　以上のように視聴情報が保存された後、第１通信装置は、映像コンテンツ受信システム３０にユーザの視聴情報の送信を要求する（Ｓ４０）。なお、本実施の形態では、上述のとおり、第１通信装置は第１コンテンツ保持装置２１に含まれるため、図７では、第１コンテンツ保持装置２１から映像コンテンツ受信システム３０に視聴情報の送信を要求している。 After the viewing information is stored as described above, the first communication device requests the video content receiving system 30 to transmit the viewing information of the user (S40). In the present embodiment, as described above, since the first communication device is included in the first content holding device 21, viewing information is transmitted from the first content holding device 21 to the video content receiving system 30 in FIG. 7. Demands.
　続いて映像コンテンツ受信システム３０において、第１通信装置が映像コンテンツ受信システム３０へのアクセス権限を有することを確認し（Ｓ４１）、第１視聴情報及び第２視聴情報を第１通信装置に送信する（Ｓ４２）。なお、第１通信装置が映像コンテンツ受信システム３０へのアクセス権限を有しない場合には、映像コンテンツ受信システム３０は、第１通信装置へ視聴情報を送信しない。また、上述のステップＳ４０及びステップＳ４１をスキップし、ステップＳ３５の後、ユーザが自発的にステップＳ４２を行ってもよい。 Subsequently, in the video content receiving system 30, it is confirmed that the first communication device has an access right to the video content receiving system 30 (S41), and the first viewing information and the second viewing information are transmitted to the first communication device. (S42). Note that when the first communication device does not have access authority to the video content receiving system 30, the video content receiving system 30 does not transmit viewing information to the first communication device. Further, the above-described step S40 and step S41 may be skipped, and the user may voluntarily perform step S42 after step S35.
　続いて、第１通信装置は、第１視聴情報及び第２視聴情報を解析し（Ｓ４３）、ユーザの嗜好に合った映像コンテンツを選択する。これに基づいて、第１通信装置は、映像コンテンツ受信システム３０に映像コンテンツを推薦する（Ｓ４４）。 Subsequently, the first communication device analyzes the first viewing information and the second viewing information (S43), and selects video content that matches the user's preference. Based on this, the first communication device recommends video content to the video content receiving system 30 (S44).
　ここで、上述の視聴情報の生成及び保存の方法について図面を用いて説明する。 Here, a method for generating and storing the viewing information described above will be described with reference to the drawings.
　図８は、本実施の形態に係る視聴情報の生成及び保存の方法を示すフローチャートである。 FIG. 8 is a flowchart showing a method of generating and storing viewing information according to the present embodiment.
　図８に示されるように、まず、ＯＴＴ－ＢＯＸ４０における視聴情報生成部４４は、受信した映像コンテンツにメタデータが含まれているか否かを判断する（Ｓ５０）。ここで、映像コンテンツにメタデータが含まれている場合には（Ｓ５０でＹｅｓ）、当該メタデータを視聴情報として生成する（Ｓ５１）。続いて、画像解析部４４ａは、当該映像コンテンツを用いて機械学習を行う（Ｓ５２）。機械学習については後述する。一方、映像コンテンツにメタデータが含まれていない場合には（Ｓ５０でＮｏ）、視聴情報生成部４４の画像解析部４４ａが映像コンテンツに対して画像解析を行い（Ｓ５４）、解析によって抽出されたメタデータに基づいて視聴情報を生成する（Ｓ５５）。 As shown in FIG. 8, first, the viewing information generation unit 44 in the OTT-BOX 40 determines whether or not metadata is included in the received video content (S50). If the video content includes metadata (Yes in S50), the metadata is generated as viewing information (S51). Subsequently, the image analysis unit 44a performs machine learning using the video content (S52). Machine learning will be described later. On the other hand, if the video content does not include metadata (No in S50), the image analysis unit 44a of the viewing information generation unit 44 performs image analysis on the video content (S54) and is extracted by the analysis. Viewing information is generated based on the metadata (S55).
　以上のようにして生成された視聴情報を、視聴情報生成部４４は、記憶部５０に保存する（Ｓ５３）。 The viewing information generation unit 44 stores the viewing information generated as described above in the storage unit 50 (S53).
　以上のように、映像コンテンツに、当該映像コンテンツに関するテキストデータであるメタデータが含まれている場合に、画像解析部４４ａは、映像コンテンツに含まれる映像及びメタデータを用いて機械学習をする。これにより、画像解析部４４ａにおける画像解析の精度を向上させることができる。 As described above, when the video content includes metadata that is text data related to the video content, the image analysis unit 44a performs machine learning using the video and metadata included in the video content. Thereby, the accuracy of image analysis in the image analysis unit 44a can be improved.
　また、映像コンテンツに、当該映像コンテンツに関するテキストデータであるメタデータが含まれていない場合に、視聴情報生成部４４は、映像コンテンツに対して画像解析をすることで視聴情報を生成する画像解析部４４ａを有する。これにより、映像コンテンツにメタデータが含まれていない場合にも、視聴情報生成部４４は、視聴情報を生成することができる。このため、当該視聴情報を用いることでユーザの嗜好をより正確に把握することができる。 In addition, when the video content does not include metadata that is text data related to the video content, the viewing information generation unit 44 generates the viewing information by performing image analysis on the video content. 44a. Thereby, even when the video content does not include metadata, the viewing information generation unit 44 can generate viewing information. For this reason, a user's preference can be grasped more correctly by using the viewing information.
　ここで、上述の映像コンテンツを用いた機械学習について説明する。機械学習において、画像解析部４４ａは、映像コンテンツの画像解析を行うことによって映像コンテンツのメタデータを抽出し、抽出したメタデータと、映像コンテンツに含まれるメタデータとを対比する。画像解析部４４ａは、当該対比の結果に基づいて、抽出したデータと映像コンテンツに含まれるメタデータとを一致させる（又は、近づける）ための抽出方法を学習する。これにより、画像解析部４４ａにおけるメタデータの抽出の精度を向上させることができる。 Here, machine learning using the above-mentioned video content will be described. In machine learning, the image analysis unit 44a extracts video content metadata by performing image analysis of the video content, and compares the extracted metadata with metadata included in the video content. Based on the comparison result, the image analysis unit 44a learns an extraction method for making the extracted data coincide with (or approach) the metadata included in the video content. Thereby, the accuracy of metadata extraction in the image analysis unit 44a can be improved.
　本実施の形態に係る映像コンテンツ受信システム３０は、視聴情報を生成し、映像コンテンツを配信する事業者に送信することができるが、視聴情報はユーザの私的な情報であるため、ユーザはその保存及び送信を希望しない場合がある。そこで、映像コンテンツ受信システム３０において、視聴情報の保存及び送信を行わないように設定できる構成を備えてもよい。このような構成について図面を用いて説明する。 The video content receiving system 30 according to the present embodiment can generate viewing information and transmit the viewing information to a provider that distributes the video content. However, since the viewing information is private information of the user, You may not want to save and send. Therefore, the video content receiving system 30 may be configured so that viewing information is not stored and transmitted. Such a configuration will be described with reference to the drawings.
　図９は、本実施の形態に係る映像コンテンツ受信システム３０において、視聴情報の保存の可否に基づいて視聴情報を処理する方法を示すフローチャートである。図１０は、本実施の形態に係る映像コンテンツ受信システム３０において、視聴情報の送信の可否に基づいて視聴情報を処理する方法を示すフローチャートである。 FIG. 9 is a flowchart showing a method of processing viewing information based on whether or not viewing information can be stored in the video content receiving system 30 according to the present embodiment. FIG. 10 is a flowchart showing a method of processing viewing information based on whether or not viewing information can be transmitted in video content receiving system 30 according to the present embodiment.
　映像コンテンツ受信システム３０において、ユーザが視聴情報の保存の可否を設定できる場合、図９に示されるように、ユーザが映像コンテンツを視聴した後（Ｓ６０）、視聴情報生成部４４は、視聴情報の保存を許可しているユーザであるか否かを判断する（Ｓ６１）。ここで、ユーザが視聴情報の保存を許可している場合（Ｓ６１でＹｅｓ）、視聴情報生成部４４は、記憶部５０に視聴情報を保存する（Ｓ６２）。一方、ユーザが視聴情報の保存を許可していない場合（Ｓ６１でＮｏ）、視聴情報生成部４４は、視聴情報を保存しない（Ｓ６３）。なお、視聴情報生成部４４は、視聴情報を保存しない場合、視聴情報を生成しなくてもよい。 In the video content receiving system 30, when the user can set whether or not viewing information can be stored, as shown in FIG. 9, after the user views the video content (S60), the viewing information generation unit 44 stores the viewing information. It is determined whether or not the user is permitted to save (S61). Here, when the user permits storage of the viewing information (Yes in S61), the viewing information generation unit 44 stores the viewing information in the storage unit 50 (S62). On the other hand, when the user does not permit storage of viewing information (No in S61), the viewing information generation unit 44 does not store viewing information (S63). Note that the viewing information generation unit 44 may not generate the viewing information when the viewing information is not stored.
　このように、視聴情報生成部４４は、予め定められた情報に基づいて、第１視聴情報及び第２視聴情報の少なくとも一つを記憶部５０に保存するモードと、第１視聴情報及び第２視聴情報のいずれも記憶部５０に保存しないモードとを切り替える。これにより、ユーザは、私的な情報である視聴情報を記憶部５０に保存しないことを選択できる。 In this way, the viewing information generation unit 44 saves at least one of the first viewing information and the second viewing information in the storage unit 50 based on the predetermined information, the first viewing information, and the second viewing information. A mode in which any viewing information is not stored in the storage unit 50 is switched. Thereby, the user can select not to save the viewing information, which is private information, in the storage unit 50.
　また、映像コンテンツ受信システム３０において、ユーザが視聴情報の事業者が管理する通信装置への送信の可否を設定できる場合、図１０に示されるように、ユーザが映像コンテンツを視聴した後（Ｓ７０）、視聴情報生成部４４は、視聴情報の送信を許可しているユーザであるか否かを判断する（Ｓ７１）。ここで、視聴情報の送信を許可しているユーザである場合（Ｓ７１でＹｅｓ）、送信部４２は、視聴情報を送信する（Ｓ７２）。一方、視聴情報の送信を許可しているユーザでない場合（Ｓ７１でＮｏ）、送信部４２は、視聴情報を送信しない（Ｓ７３）。 Further, in the video content receiving system 30, when the user can set whether or not the viewing information can be transmitted to the communication device managed by the provider, as shown in FIG. 10, after the user views the video content (S70). The viewing information generation unit 44 determines whether the user is permitted to transmit viewing information (S71). Here, when the user is permitted to transmit viewing information (Yes in S71), the transmission unit 42 transmits viewing information (S72). On the other hand, when the user is not permitted to transmit viewing information (No in S71), the transmission unit 42 does not transmit viewing information (S73).
　なお、視聴情報の保存の許可、及び、視聴情報の送信の許可は、それぞれユーザ毎の設定としたが、それぞれコンテンツ毎に設定できてもよい。 Note that the permission to save viewing information and the permission to transmit viewing information are set for each user, but may be set for each content.
　このように、送信部４２は、予め定められた情報に基づいて、記憶部５０に保存された第１視聴情報及び第２視聴情報の少なくとも一つを第１通信装置に送信するモードと、記憶部５０に保存された第１視聴情報及び第２視聴情報のいずれも第１通信装置に送信しないモードとを切り替えてもよい。これにより、ユーザは、私的な情報である視聴情報を第１通信装置に送信しないことを選択できる。 As described above, the transmission unit 42 transmits at least one of the first viewing information and the second viewing information stored in the storage unit 50 to the first communication device based on the predetermined information, and the storage. The mode in which neither the first viewing information nor the second viewing information stored in the unit 50 is transmitted to the first communication device may be switched. Accordingly, the user can select not to transmit viewing information that is private information to the first communication device.
